print: oh dear, i have reworked the progress bar again 

- rework the progress bar a little bit, basically removing the [ and ] to give a more
  modern aesthetic.

- if utf-8 locale is enabled, use unicode codepoint 0x2588 instead of # to give the
  progress bar a nicer look.

- if APK_PROGRESS_CHAR environment variable is defined, use the character defined there
  for the progress bar.
